Inspired by CGB's UW Counterpost deck, this greedy deck endlessly floods your hand with answers to anything your opponent might throw at you.

Highlights

• Shigeki + Dryad's Revival
  Endless recursion. Need I say more?
  
  
• Phyrexian Arena
  The greed machine. Will you risk losing life every turn for additional cards? You bet you will. And you'll thrive doing it.
  
  
• Union of the Third Path
  Prolongs matches against aggro, and pays off your debt to Phyrexian Arena. Chain these together and watch your life total explode.
  
  
• Kaya, Intangible Slayer
  Stabilizes you with her card draw, then Lightning Helixes your opponent every turn, which just so happens to be more than enough to pay for two Phyrexian Arenas 🤔. You may even want to turn the greed to eleven by drawing deeper and deeper to hit your Shigeki to secure the lockdown.
  
  
• Dryad's Revival
  Brings back Union for explosive life gain. Brings back Kaya for huge value. Brings back Shigeki for endless recursion. Bear in mind that this card is the only spell in your deck that can bring back Kaya. And you need to have both if you think you'll need to include her in the endless recursion.
  
  
• Turn the Earth (TTE)
  This deck is the shell needed to push this card over the edge into playability. It does so many things it warrants a sub-list.
  
  
  • It keeps you from decking yourself. You can draw 5-9 cards a turn and feel safe doing so because of this safety net. The most basic form of this combo is taking a Turn the Earth and sending your other Turn to Earth to your empty library, drawing your next card, and repeating this process. This is a strategy that makes you immune to milling effects that would kill you, as it stops them from forcing you to exile a TTE. The more realistic form of this is sending a TTE and two other cards to the bottom of your library. There's a special combo here that will be revealed later.
    
    
  • It's a graveyard shield. Leaving a green mana source open allows you to cast this in response to graveyard-hate. You can rescue all of the big cards your opponent is trying to get rid of. Namely, Shigeki, Revival, and Kaya. If your suspect your opponent is going to cast a Trespasser or a Farewell, just leave a green source open.
    
    
  • It's a curve-filler. Have an extra green mana lying around? You've just signed up for a free trial of the graveyard shield! If you don't need it for that, it's 2-4 extra life. Just used your Shigeki to grab a bunch of cards but didn't hit the land to cash in for an additional card? That's an open land that can be redeemed for 2 life. In fact, if you have nothing better to grab, take a TTE out of your graveyard with Shigeki, and then put it back there for 2 life before you begin your turn.
    
    
  • It can bloat your opponent's deck. Tutoring lands out of your deck is called "thinning your deck" because it makes it oh so slightly more likely to draw non-land cards. This card does the opposite. Whenever you find yourself with unused targets, consider returning lands to your opponent's library so that they're more likely to draw lands at a critical time when they need to draw threats.
  • It de-"nonbo"s your Farewells. Sometimes you just have to exile your opponent's graveyard. Which means you have to exile your own. Typically, this is a potentially nasty proposition that requires really weighing your options. With TTE, many avenues are open to protecting your most valuable graveyard targets while you do this.
    
    
  • It is hugely disruptive to graveyard plans. 
    • It shuffles away bolts before Bloodthirsty Adversary can recur them.
    • It shuffles away Squee, Dubious Monarch, and Phoenix Chick. All while gaining life in the process.
    • It shuffles away Tenacious Underdog and Takenuma, Abandoned Mire picks (be aware it doesn't target).
    • It shuffles away all of the big black creatures targeted by The Cruelty of Gix and Gix's Command.
    • It shuffles away Yotian Frontliner and Valiant Veteran
    • It shuffles away mono-blue instants and sorceries, sapping power from Haughty Djinn and delaying Tolarian Terror.
      
      
  • It is incredibly flexible. When placed next to Shigeki and Dryad's Revival, the number of ways you can utilize this card gets complex. But with that complexity comes flexibility. There are many decisions to be made based on factors like what you are fetching this card with, what's the necessary time to flashback TTE and Revival, and How protected and stable are your recursion and library chains without this card? Are you casting one side or both? Are both of your TTEs out of your library? Where are they? Where should they be? Which ones do you use? Don't be surprised if you find yourself suddenly faced with multiple decisions based on this one card. Take a moment to weigh your options and plan the best course.
    
    
• Argoth, Sanctum of Nature
  Argoth? Or Mirrex? This is a good question. Mirrex costs less, activates at instant speed, and comes with Toxic 1. Argoth costs more, has a color requirement, is sorcery speed, and mills a lot of cards. So why use the Argoth? Is it because I had no Mirrexes? Yes, but I've certainly warmed up to this legendary tree. The 2/2 body can block and is twice as big as the mite. This matters when you have nothing else to do but are still on the defense. You can build up a wall of bears that chump or trade with your opponent's creatures until you can draw something to stabilize. The mill effect has a shot at putting Revivals and TTEs into your graveyard, as well as giving you a boost in selection for your Shigekis and Revivals. When it happens on turn 5, it curves into a Shigeki for 4GG and Farewell. And because we have enough to keep our decks going forever, you can be quite greedy with this and suffer little to no negative repercussions. In addition, you can use this to block the mites your opponents make with their Mirrex. Hah!
  
  
• Turn the Earth + Union of the Third Path
  Your library is depleted and you have a decision to make: "What three cards should my library be?" You look at Union of the Third Path. "Obviously not," you say. "Why would I want to pack my library with cards that do exactly what I don't want to be doing?" A reasonable assessment. One would think.
  
  Imagine if you will, a shuffled library consisting of a Turn the Earth and two Unions of the Third Path. You have an abundance of mana available to you at this point. And let's say four cards. So you draw your first Union, gain 5 life, which draws your second Union, which gains you 5 life, and draws your TTE, which gains you another 2 life and lets you shuffle the three cards you need to endlessly enjoy this process. This is the most basic form of this combo.
  
  As soon as you have access to any card draw spells or recursion cards, you unlock the ability to dump all of your mana into a massive life gain machine that pumps out 40-50 life per turn. Look for ways to do this by strategically timing the draws from Phyrexian Arena, or keeping it going with Kaya. If you have a Revival or a Shigeki, use it to get more TTEs and Unions into your hand so you can keep the chain going until you come close to running out of mana.
  
  
• Field of Ruin
  Together with Shigeki and Revival, this answer to Mirrex can be used again and again. In the late, late game, it forces lands out of an opponent's dwindling library and then begins to stone rain their nonbasic lands. We have two basics in our library for this, with the idea that once we are far enough in the game to want more than one, going down a land won't be a significant cost.
  
  
• You can trap your opponent in a neverending game of Magic until they concede.
  Here is your reward for checking this write-up. When your opponent is out of options, you don't have to drain them out with Kaya or beat them down with bears. You can simply sit back and let them deck themselves. Evil enough, eh?
  
  But what if you wanted to take it a step further? Perhaps your opponent has been roping you but refuses to concede? Perhaps you know your opponent to be the real-life Joffrey Baratheon? Or worse: They play UW Counterpost.
  
  Just when they expect to draw from their empty library and embrace the sweet release of death, you decide to make one of your TTE targets their Atraxa. "Sweet!" they think to themselves. They play the Atraxa but get no card draw. "That's alright, it's still a 7/7 flying vigilant lifelink-.." Their thought is cut off by Sheoldred's Edict. They end their turn and you channel Shigeki, picking up TTE, Dryad's Revival, Union, and Sheoldred's Edict. You cast Revival, getting Shigeki back, you cast TTE putting the other TTE back into your library along with another union, and the Atraxa into theirs. They draw their Atraxa again.
  
  You have imprisoned your opponent in an endless game of magic. Until they give up and just let the cards spill out of their hand, they will continue to play against an opponent that packs half a dozen removal spells for their threats. Curated exactly to deal with those threats. You don't even have to give them threats. If you give them creature removal, cantrips (self-decking thwarted by TTE), and burn spells, they'll be sitting there with nothing they can possibly do except see how high your life total can get, or concede.
  
  If that all seems too evil for you, consider it the "pacifist ending." In true Abzan fashion, you don't have to kill them. You're just asking them with vindication burning in your eyes nicely to go away.
  

--- Some miscellaneous information ---

Always put a stop on your upkeep when you're nearing the end of your library. You must choose whether to Turn the Earth at the end of your opponent's turn, or at the beginning of your turn. If you begin your turn without a stop placed, you will draw from an empty library before you have a chance to cast Turn the Earth.

As long as you have TTE in your graveyard, you can protect a channeled Shigeki from being eaten up when used in response to a Farewell. As soon as the cards are returned, you use TTE to return the Shigeki. There is quite an array of ways you can approach just this scenario.

If you have a TTE in your hand, and the other in your graveyard, and you have cards to rescue from being exiled, you should usually choose to flashback the one in your graveyard. It's more valuable to keep a TTE in your hand.

Note that the auto-tapper is less likely to leave a green mana source open after using Shigeki. Be mindful.

A niche strategy, but you can bait your opponents into using Farewell by casting Shigeki on your turn with mana open for TTE when they try to exile the Snake on their turn.

Against UW Control, Try to save your Farewells to snipe your opponent's Devious Coverups from their graveyard. Remember that you have some wiggle room to sacrifice Shigekis and Revivals to Farewell in order to rescue your TTEs. That is if you feel like the library loop is something they can't beat.

Before I got my second Phyrexian Arena, I ran three Dryad's Revivals. Doing so significantly bumps up your recursion potential. One aspect being that you can flash back a Revival without losing the ability to endlessly recur Kaya. However, it comes with a similarly significant drawback to your game-closing and combo potential. Don't be afraid to experiment with the numbers.
